1-Phenyl-3-methyl-4-acyl-pyrazolone-5 and its application for the extraction of uranium(VI) and other metal ions
1-Phenyl-3-methyl-4-acyl-pyrazolone-5 derivatives having carboxylic acid groups in the acyl moiety were synthesized from 1-phenyl-3-methyl-pyrazolone-5 and cyclic anhydrides and were identified using various methods. Among numerous acyl derivatives prepared, succinyl pyrazolone appeared to be the most effective extractant especially for uranium(VI) in chloroform as a solvent. Carboxylate participation in the complex was invoked and qualitatively discussed to help interpret the results of extraction using succinyl pyrazolone. These results indicate that the introduction of various functional groups in the acyl moiety may be useful in manipulating the molecule for analytical purposes. 17 references, 11 figures, 4 tables.
